A triple threat of winter storms was roaring toward the nation’s midsection Sunday, threatening travel headaches through the week as the Upper Midwest hunkered down in biting cold and wind chills that could reach minus-50 degrees.

At least three storms will be responsible for the threat of ice and snow from Sunday through Thursday, AccuWeather reported. The storms will be fueled by moisture coming off the Gulf of Mexico and colder air sweeping south. In some areas, the precipitation will be almost constant for days, AccuWeather said.

“Cold air will plunge far enough south to set up a weather battle zone much of the week,” AccuWeather senior meteorologist Alex Sosnowski said. 

One major concern is for a glaze of ice that could cause dangerous travel conditions from eastern Oklahoma into northwestern Arkansas and southern Missouri, he said.

In some places, it’s just ridiculously cold. The National Weather Service office in Pocatello, Idaho, warned of highs Sunday struggling to climb above -10°F in some areas.

“Tonight, everyone will see single and double digits below zero,” the office tweeted. “Coldest temperatures will fall into the -30s with wind chills down to -50°F.”
